# The second root of a number is a value that, when multiplied by itself, gives the number. The SQRT function in Excel returns the second root of a number.

1. First, to get the square root of a number, multiply the number by itself. For example, 16 = 4 * 4 or 16 = 2.4%

Tip: Press SHIFT and 6 to enter the symbol.

2- The second root is 16 times 4.

3- Instead of using the SQRT function, you can also use a factor of 1/2. Do not forget the parentheses.

4. If a number is negative, the SQRT function returns the error! NUM #.

5. You can use the ABS function to remove the negative sign (-) from the negative number.

Excel has no internal functions for calculating the nth root of a number. To calculate the nth root of a number, simply multiply that number by 1.

6- For example, in 5 * 5 * 5 or 3.5, 5 has reached the power of three.

7- The third root of 125 is equal to 5.

8. For example, 2 * 2 * 2 * 2 * 2 * 2 or 2.6 increases the number 2 to the power of 6.

9- The sixth root is 64 times 2.
